I am going to ask a dumb question....do you have it in neutral and the brake mashed when you switch to 4WD LOW? I believe that is what my book says to do.

If this is a 2004 Heritage ( old body style ) and the transfer case is known to lock in ( check with truck jacked up, shift into 4WD and try to turn front drive shaft ), the next item to look at is the vacuum disconnect motor for the front axle. This is on the front axle, and will move when shifted into 4WD
It is item #10, on this parts diagram
If you do not have movement in this, check the vacuum lines with a vacuum pressure gauge, to see if vacuum is being applied ( Pink line is 2WD w/ vacuum is operation, Blue line is 4WD w/ vacuum operation ). If no vacuum at the lines, check them back to the vacuum shift solenoids

DTC code p0174 means "System too lean (Bank 1)"
Basically this means that an oxygen sensor in bank 2 detected a lean condition (too much oxygen in the exahust). On V6/V8/V10 engines
, Bank 2 is generally the side of the engine that doesn't have cylinder #1.

No problem P0506 is IDLE CONTROL lower than expected. By disconnection the battery you erased the adaptive stratagies. Put the A/C and give part throtttle about 1500 RPM for 1 minute or until operating closed loop and the stratagy will get restored even as you drive it.
